A fuel electrode for a solid oxide electrochemical cell includes: an electrode layer constituted of a mixed phase including an oxide having mixed conductivity and another oxide selected from the group including an aluminum-based oxide and a magnesium-based composite oxide, said another oxide having, supported on a surface part thereof, particles of at least one member selected from nickel, cobalt, and nickel-cobalt alloys.

A combustion catalyst is disclosed which is composed of a durable support containing a plurality of mutually partitioned and independent combustion gas flow paths and an active catalyst formed mainly of palladium and/or palladium oxide and deposited in the form of a coating on the inner wall surfaces of the combustion gas flow paths and characterized in that the deposition of the active catalyst in the form of a coating on all the inner wall surfaces is omitted in part of the whole of the combustion gas flow paths. The mutually partitioned and independent combustion gas flow paths which are provided for the durable support jointly form an aggregate of opening parts in the pattern of gratings and these opening parts have a square, rectangular, triangular, or hexagonal cross section. Thus, the durable support constitutes a so-called honeycomb structure.
